To all whom it may concern: v V

Be itknown that I, JOSEPH GoULDBonnN, a subject of the King of England, residing at Leicester, Leicestershire, England, have invented certain Improvements in VVOrk- Supports for Shoe Machinery, ofwhich the following description, in connection with the accompanyingv drawings, is a specification, like reference characters on thedrawingsindicating like parts in the several figures. This invention relates to work supports for use in shoe machinery, and more par ticularly to machines of the type in which a work support is arranged to be canted to allow the workto be 'placedthereon and then returned to normal position to bring the work into the proper relation with the operative tools of the machine. Of such machines, a machine for attaching'heelsto hootsand-shoes forms a typical example. In machinesof this type there is frequently employed a jack hinged so that it can be swung forwardly and, canted to facilitate the fitting thereon ofa boot or shoe, the jack being thereaft'er returned to bringthe heel seat of the shoeinto alinement with the heel. Then this relation has been established thetwo parts oft-he work are pressed together and then the heelis securedto the sole by nails driven, in the usual manner. In, machines of this construction it sometimes happens that, the heel seat is not quite level, there .is developed a tendency to cant the work support, when the pressure is exerted,with the result that the nails are improperly driven or that theheel shifts in relation to the shoe and isfnot securedin l )Vith these conditions in view it is an obect of the present invention l30-PTQV1d6 a .work supportwhich shall possess all the benefit of the canting movement'for the easy reception and fitting of the work, and which shallhe so constructed and arranged as to possibility of canting under .With this end in view an important feature of the invention'fconsists broadly in a swinging or canting ack arranged, for use as one of two cooperating work pressing members and being provided with means for automatically, locking said jack when i re- Specification of Letters Patent;

in another direction removes the jack from engagementwith such stop, leaving thejack free to be canted- .The bodily sliding move mentof the jack is advantageous in that it takes the jack ,out of alinement with'the op-' posed work'engaging member when the'jack p is moved into work receiving position and so afiords clearance forfputtingworkonj or Another feature of the invention consists 111' so constructlng the stop for the jack gasto allow the latter tobe drawn forwardly and canted by a single movementpreparatory to receiving the work and also to be returned to operative position by another single movement to position the work- These and other features ofthe invention will be best understood ant:l. appreciated from the following description of ,a preferred embodiment thereof selected forv pur- Fig. 2 is a similar view showing theljack h in its canted or work receiving pos tlon;

1,195,134, granted Aug. 15,, 1916, on myap plication Serial No. 722,270,1iled'Septem- I v,ber 25, 1912, although it" is to be'understood thatfthe inventionis not vlimited to this or any other particulartypegof machine, but has-a general application. 'In the present machine, as in ,thelmachine of' said appli-' c'ation,'the lasted'bo'otor shoe is placed upon the jack and is then brought into operative relation with the heel'npon'theynail block. Thereafter the ma'chinejis started, and nails are driven from said block into the heel and.

80 poses of illustration and shown in they heel seat of the 'shoeto secure them to gether.

In the illustrated embodiment of the invention the jack 2 is pivotally mounted upon a transverse pin l which projects from a lug formed on a sliding plate 6. The plate 6 is mounted to slide from'front to rear in guideways 8 formed on the lower end of a post 10 mounted for vertical movement in the machine frame 12. The sliding plate 6 is kept in the guideways by gibs 9 which are secured to flanges, formed on the lower end of the post 10.

The jack 2 hangs downwardly from its pivot 4; and is adapted to be moved from the I serve to hold the jack in its canted position.

'Thejack is prevented from being swung in an opposite direction or rearwardly by a projection 24 on the jack that contacts with a corresponding projection 26'on the sliding plate 6 when the jack is in its ver' tical and rearmost position. I

Secured by screws 28 to the jack 2 is an arm 30 which projects rearwardly at substantially right angles to the jack, the jack and arni 3O constituting, in fact, a bell crank lever. Adjacent to the rear end of the arm 30 there is provided a cam roller 32 which is received in a slot 34; formed in a plate 36. The plate 36 is secured to Or formed as a part of one of the gibs 9 before-mentioned in order that the cam plate 36 maybe held stationary while the arm 30 and the roller 32 are free to be moved with the jack 2 and sliding plates 6 forwardly and rearwardly, from and into operative position. The slot 34 in the plate 36 extends from its outer end horizontally at first and then. downwardly along a curved path, the center of curvature of which .beingfthe axis of the jack, that is to the pivot pin 4.

From'the foregoing description it will be apparent that when the jack 2 is in its operative position it will be held rigidly against all tendency to cant by the engagement of the roller 32 with the horizontal walls of the straight part of the slot 34. When the, jack "isdrawnforwardly with the sli ding'plate 6 the roller 32 will travel along the straight part of the slot '34 until it reaches, the downwardly curved, portion thereof; .When'the rol'lerreaches'this part of the slot the jack will be free tobe swung The catch 18 and forward position.

The jack will then'be 22 and the catch member 18 until it"is desired to return it to its operativeposition. This may be effected by pressing the ack ,rearwardly, the spring plunger 22,yielding to release the catch member.

Bythe construction and arrangement of the slot 3% the jack is free to be moved out? wardly of the machine and canted for the removal and replacement of the work by a single pull upon the jack by the operator, and returned into operative position by a single continued push. Moreover, having been moved by the operator into oneposition or the other, the jack remains in such position as long as desired.

Having now described my invent on, I claim as'new and desire to secure by Letters Patent of the United States 1. A work support for shoe machinery,

comprising a slide movable from. front'to real in a substantially horizontal path, a

jack pi\'*otally mounted upon the slide, and
